Weinman Pumps CV Series 320 inline centrifugal pumps are designed specifically for heating, air conditioning, commercial building and municipal applications. Suction and discharge nozzles are located 180° apart on the same centerline for mounting directly in a pipe line. This eliminates critical pipe alignment for ease of assembly and minimum pipe strain. The inline design eliminates the need for costly foundations and guarantees minimum space requirements. The motor and bracket assembly can be removed from the casing without disturbing the piping. The impeller, mechanical seal, shaft sleeve, and wear rings are therefore accessible for easy maintenance. Mechanical seals and bronze wear ring(s) are supplied as standard on certain pumps. A built in purge system assures proper flushing and venting of seals. A NEMA frame motor with a JM shaft is standard on most models. The motors are specifically designed for mechanical seal applications. Controlled tolerances and adequate bearings assure long life.
